>> Product Description
    The Powell lens resembles a round prism with a curved roof line. The lens is a laser line generator, stretching a narrow laser beam into a uniformly illuminated straight line.
   The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens. A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam. The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends. The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production.

   Powell prisms (also called laser linear generator lenses) are optical marking prisms that can be optimized for the input of laser beams with a diameter of 0.8mm. After passing the laser beam, it can be optimized into a straight line, with uniform optical density, good stability and good linearity. Unlike the cylindrical lens that generates the central hot spot and the fading edge of the Gaussian beam, it can eliminate the distribution of the central hot spot and the fading edge of the Gaussian beam, and form a straight line with uniform energy distribution. The full fan angle ranges from 1° to 120°. The standard specifications are 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, 110° and 120°.
  The Gaussian laser beam passes through an ordinary cylindrical lens to produce a linear uneven distribution, while Powell has a complex two-dimensional aspheric surface on the top of the prism. A large amount of spherical aberration is generated through the laser, and the optical path is redistributed, reducing the center of the light. Area, increase the edge of the light, form a uniform line, suitable for various biomedical, automobile assembly, food processing and machine vision applications.
   Used for positioning, laser marking machine, processing marking positioning, building target marking, laser scanning system, measuring equipment. It is suitable for various machine vision applications; from biomedicine to car assembly to chocolate chip cookie production; various online inspections of mobile phones, aircraft military applications, and shipyards.
